Step-by-step explanation:
Because they do a school show every Monday and a library show every fifth day of the weekday and weekend so all you have to do is count the days from the Monday they’re doing a show at both places but keep in mind that they do library shows on the fifth day of the weekend and weekday that’s how you get to 19
Answer:
or ![x=-1.33](https://tex.z-dn.net/?f=x%3D-1.33)
Step-by-step explanation:
From the triangle shown,
EG = DG
Plug in
for EG and 16 for DG. Solve for x.
![3x^{2} -8x=16\\3x^{2} -8x-16=0](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20-8x%3D16%5C%5C3x%5E%7B2%7D%20-8x-16%3D0)
The above equation is a quadratic equation of the form
with a = 3, b = -8 and c = -16.
Now, using the quadratic formula, we solve for x.
± ![\frac{\sqrt{b^{2}-4ac } }{2a}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7Bb%5E%7B2%7D-4ac%20%7D%20%7D%7B2a%7D)
Plug in 3 for a, -8 for b and -16 for c.
± ![\frac{\sqrt{(-8)^{2}-4(3)(-16) } }{2(3)}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B%28-8%29%5E%7B2%7D-4%283%29%28-16%29%20%7D%20%7D%7B2%283%29%7D)
± ![\frac{\sqrt{256} }{6}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B256%7D%20%7D%7B6%7D)
± ![\frac{8}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B3%7D)
or
![x=\frac{4}{3}-\frac{8}{3}=-1.33](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B4%7D%7B3%7D-%5Cfrac%7B8%7D%7B3%7D%3D-1.33)
Therefore, possible values of
are -1.33 or 4.
